title: [Antitumor activity of N-(5-indanylsulfonyl)-N'-(4-chlorophenyl)-urea, LY 186641 against various human cancers using subrenal capsule assay].
abstract: An analog of diarylsulfonylurea, LY 186641 has a broad spectrum activity against murine solid tumors including Colon 26 and LX-1. Preclinical evaluation of the anticancer activity of LY 186641 using the subrenal capsule assay was performed in fresh human tumor samples derived from 87 patients with various cancers and 70 (80%) samples were evaluable. The overall chemosensitivity rate of LY 186641 was 37% and the average tumor growth inhibition rates (TGIRs) of malignant lymphoma, esophageal cancer and colorectal cancer were 51 +/- 19%, 51 +/- 20% and 48 +/- 12%, respectively. The antitumor effect obtained by LY 186641 was comparable to that of the standard anticancer drugs including adriamycin, 5-fluorouracil and cisplatin evaluated in this assay simultaneously. Based upon these results, LY 186641 is considered to have antitumor activity against some human cancers.
